lBARREL-STAVE-NUMBERING APPARATUS.

Specification of Letters Patent.

Patented May 21, l'tltlld.

Application filed November 20, 1917. Serial No. 202,917.

1 zone of the United States, residing at the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Barrel-Stave- Numbering Apparatus, of which the follow ing is a specification.

Barrels and other cylindrical containers of the stave type are formed at a cooperage plant and then in a knocked down condition, in order to save transportation space, are shipped to the point to be used and then re-assembled. When the staves of the bar-- rel or receptacle are temporarily assembled and are temporarily held together by the temporary hoops it is necessary to mark the staves or indicate the same in such manner so that the staves after the barrel or receptacle has been knocked down and it is desired to re-assemble the same, may be positioned properly relative to each other. The present practice in so marking the staves of a barrel or other cylindrical container is to employ a stencil for positioning over the temporarily assembled barrel and to use 1n connection therewith a suitable brush for forcing the ink through the openings of the stencil onto the staves, one mark or a portion thereof being made on each stave in some consecutive order so that it will be possible to properly assemble the staves with the staves consecutively arranged after the barrel has been marked out. This is a costly and slow proposition, and the capacity of one operator in performing th1s operation is very limited thereby in a cooperage plant of any great output several markers or stencilers are required.

The present invention has to provide a construction wherein this operation of marking staves of a barrel when temporarily assembled together is accomphshed while the barrel is being rotated and worked in a crozing, chamfering or hollowing machine or in fact any type of machine for operatin on a temporarily assembled barrel wherem the barrel is rotated while the same is being operated upon, thereby dispensing with the marking operators and marking the barrel while some other required work on the same is being performed, thereby reducing the cost of marking a barrel to aminimum and insuring that the staves of each barrel-will be properly marked as the function of marking the same is performed during some necessary operation on the barrel..

The invention consists broadly in a marking member provided with suitable marking characters supplied with a marking medium by a suitable member in contact therewith, the marking member being held in contact with the staves of the barrel during the rotation thereof so that indications on the exterior of the staves circumferentially of the barrel will be made on one complete rotation of the barrel in its operation. The marking member is preferably moved a slight distance longitudinally of the barrel to prevent the overlapping of the opposite ends of the marking on the barrel.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in To more fully comprehend the invention reference is directed to the accompanying drawings, wherein,

Figure 1 is a view in side elevation of a suitable barrel operating machine or apparatus, with the preferred embodiment of our invention applied thereto.

Fig. 2 is a vertical sectional View of the barrel operating mechanism illustrating the printing and marking rollers and the manner of mounting the same.

Fig. 3 is a view in detail of the printing or marking member; and

Fig. 4, is a view in detail of the mechanism for causing longitudinal movement of the printing or marking member relative to the barrel on each revolution of the same.

Referring more particularly to the accompanying drawings, wherein like characters of reference designate corresponding parts throughout the several views, 1, indisame.

cates the base or frame of a suitable crozing, chamfering or hollowing machine or any type of machine for operating on a temporarily assembled barrel, and wherein thebarrel is rotated during such operation. In the embodiment of the machine illustrated, suitable cylindricalstandards 2 slidable longitudinally of the base or frame 1 are employed, the same being moved by suitable lever mechanism 3 to engage the opposite ends of a temporarily assembled shaft? and driven by a belt 8. Cooperating with each of the crozing members 6, is a suction duct 9, for withdrawing the severed material from the interior of the barrel. As both of the crozing mechanisms for acting on-opposite ends of the barrel are identical, it is only thought necessary to illustrate one.

Supported by brackets 10, one extending upwardly from one of the members 2 and the other extending upwardly from the sliding base 11 supporting said member 2 is a supporting shaft 12 fulcrumed at its opposite ends in bearings 13 and carrying intermediate of its length a suitable arm 14 through an opening in the outer end of which extends an adjustable link 15 connected at its lower end by a crank 16 with the lever 3 for operating the member 2 associated therewith. A spring 17 positioned intermediate the upper surface of the outer end of the arm .14 and a plate 17 carried by the upper end of the link 15 provides a yielding connection between the link and arm, as 1n Fig. 1 of the drawmgs. On the V outer end of the supporting shaft 12 is carried a suitable U-frame 18, in which is rotatably mounted a suitable marking or printing roller or wheel 19 supported by a shaft 20 projecting at its opposite sides from the I hub 21 thereof, the opposite ends of said shaft being movable longitudinally through bearings 22 in the outer ends of the side walls of the U-frame 18. The marking or printing roller or wheel carries on its pe- 'ripheralsurface suitable marking means or characters 23, preferably arranged in some fixed manner, if numbers or letters are employed, the same are preferably arranged in a consecutive manner. An inking roller or other supply 23 rotatably mounted in a frame 25 pivoted as at 26 to the rear of the U- frame 18 is normally maintained in frictional contact with the periphery of the printing wheel 19 by the spring 27 and this supplies ink or marking material to the marking means 23 011 each revolution of the roller or wheel 19.

To prevent the characters 23 on the roller or wheel 19 from overlapping as printed on the barrel on successive revolutions thereof, it is preferable that the characters be printed on the barrel in a spiral circumferentially thereof and to accomplish this result, the printing wheel 19 is normally maintained in the position as in Fig. 3 of the drawings by a spring 28, the free end of which contacts with one face of the hub 21, said spring being supported by the U-frame 18. A spiral guide 29 is carried by the U- frame 18 at'the opposite side of the hub 21 from thespring 28, and with said guide cooperates a guide finger 30, carried by the hub 21. It will thus be apparent that during each complete revolution of the wheel 19, the finger 30, in its travel on the guide track 29, will cause longitudinal movement of the shaft 20 in the bearings 22, and thus cause a spiral printing of the characters on the barrel staves. The inking roller 24 is of such width that the printing roller is in contact therewith during the full longitudinal movement of the shaft 20 and the bearings 22.

The operation of the levers 3 to move the guide member 2 into contact with opposite ends of the assembled barrel 4 in the oroz ing of the ends thereof, causes one of the levers 3 to depress the arm 14, which forces the characters 23 of the wheel 19 into contact with the outer surface of the barrel adjacent one end thereof, consequently on the rotation of the barrel in the crozing thereof, the characters 23 will be printed on the outside of the staves thereof, and as the crozing is performed in a single revolution only a single revolution of the printing wheel 19 is required. In order to prevent the characters printing on the barrel from overlapping, the wheel in its rotation is moved a slight distance longitudinally of the barrel due to the movement of the finger 30 on the spiral guide 29. On the return of the hand levers 3 to their normal position the Weight of the rear end of the U-fra1ne 18 raises the roller 19 from in frictional contact with the barrel; it will thus be apparent that an apparatus has been provided whereby the position of the staves of a temporarily assembled barrel relative to each other may be readily indicated during one of the necessary operations on the barrel, so that when the barrel is knocked down and it is desired to re-assemble' the same, the position of the staves may be readily ascertained and the barrel as originally temporarily constructed may be again assembled.

Having thus described our invention what is claimed as new and desired to be protected by Letters Patent is:
